How are people supposed to win if 3 teammates are working with them to play denial?

I just witnessed my first game of Denial.
Basically what Denial is:
- One core team member builds a build that counters other compositions.
-The other two build kits that mimic and copy parts of the other 5 members of the match.
What this does:
The 5 other comps cannot complete champs beyond 2 stars. The counter builder CAN.
The one I just saw basically played Denial of "Yordle/Wild"
2 People built identical builds, while the 3rd built counter Yordle.
They didn't switch to this until after about round 13, but kept the components in their decks.
